Hikvision DS-9632NXI-I8/S – 32-Channel 2U 4K AcuSense Network Video Recorder
The Hikvision DS-9632NXI-I8/S is a 32-channel 2U NVR built for enterprise sites that need RAID-backed storage alongside deep-learning analytics. Specifically, it accepts up to 32 IP camera inputs at resolutions up to 12 MP, and since it carries no built-in PoE ports, all cameras connect through an external network switch. As a result, installers should plan switch infrastructure and cabling separately from the recorder itself.
In addition, facial recognition and face picture comparison run on this recorder, supporting up to 16 face libraries with up to 10,000 stored faces. Meanwhile, perimeter protection covers up to 4 channels with human and vehicle analysis, which in turn reduces false alarms caused by leaves, shadows, or small animals. Furthermore, eight SATA interfaces accept drives up to 10 TB each, giving up to 80 TB of total capacity, and the recorder supports RAID 0, 1, 5, 6, and 10 for data redundancy. On top of that, built-in POS integration overlays transaction data on live view and playback, while dual HDMI and VGA outputs support flexible local monitoring.
Key Features
- 32-channel capacity at up to 12 MP – supports a large mixed-resolution camera fleet on a single recorder.
- RAID support – RAID 0, 1, 5, 6, and 10 protect footage against drive failure, suiting sites where data loss isn’t an option.
- Eight SATA bays – supports up to 10 TB per disk, giving up to 80 TB of total on-device storage.
- Facial recognition and perimeter protection – identifies faces and flags human/vehicle movement across up to 4 channels, reducing false alarms.
- Dual HDMI outputs – HDMI1 reaches 4K resolution, with HDMI2 available for a second independent display.
